Abstract (en)

A ferroelectric memory comprising a select transistor and a ferroelectric capacitor is characterized in that the ferroelectric capacitor includes a dummy capacitor and a memory capacitor the first electrodes (storage node electrodes) of which are connected to one of the source and drain of the select transistor and which draw the same hysteresis curve, the second electrodes of the dummy capacitor and the memory capacitor are connected to a first plate line and a second plate line, and the potentials of these plate lines are set so as to polarize the dummy capacitor and the memory capacitor in opposite directions to each other with respect to the first electrode. <IMAGE>
